Specification of Letters Patent. Patgngd glug. 2g, TL922 Application filed .Tune ,3, 1920, Serial No. 386,332. Renewed .Tune 3, 1922. Serial No. 565,744.

To all w wm t may concern Be it known that I, HARRY EDWIN MACCAMY, a citizen of the United States,

residing at Los Angeles, in the `county of Los Angeles and State of California, have invented a new and useful Condenser and tion.

This invention relates to devices for condensing and cooling substances passingthrough the device.

. @ne of the objects of this invention is to cool the body of the device thereby facilitating the operation of the device.

Another object is to cool the body of the device in conjunction with and by the cooling system of the device for facilitating a cooling and condensing of the matter passing through the device.

Another object is to provide a device of this type with double walls for keeping the inner` condensing walls in a condition similar to that of the condensing tubes in the device.

Another object is to increase the efficiency of devices of this type.

Another object is to provide a number of individual cooling units, independently receiving and discharging` a cooling medium so that the efficiency ofthe .several indilvidual units can be equally wellfcontrolled.

Another object is to provide a number of individual cooling units, so that any of the units may be repaired or cleaned without impairing the efliciency of the other units.

Another object is to provide a suitable number of cooling units, each of the units receiving and discharging a cooliiigmedium independently of the others so that the passing matter to be cooled meets constantly and continuously freshly cooled surfaces so as'to insure very rapid condensation and cooling,

'which makes it possible to obtain a high degree of vacuum with the minimum amount of cooling medium. l

Another object is to provide tube plates into which all cooling tubes are equally well sealed independently of the body of the device.

Another object is to provide a number of v'closing plates so as to cover the ends of different units of cooling tubes such plates being provided with return pockets for allowing the cooling medium from one tube to I pass over to and through the nearest next which- Cooler, of which the following is a speciicaf Fig. 1 is a front elevation of the device, one cover plate being removed and a portion being broken away to show inside construction and details. y

2 is aside elevation of the device. Fig. 8 is a horizontal cross section of the device on line 3 3 of Fig. 1.

Fig. 4 is a fragmentary detail midsectionalv view of one end of a cooling tube as secured within the tubeplate.

Fig. 5 is a fragmentary sectional illustration of body, tube plate, and cover plate,

held together by a common bolt, the tube plate independently to the body andthe cover plate also independently to theL body outside of the tube plate.

Fig. 6 is a fragmentary sectional illustra;

tion oftube plate and cover plate connected by ashort stud bolt.

Fig. 7 is a fragmentary illustration in which the outlet tubes or the outlets of the l device are arranged to communicate with a single common outlet tube 26, instead of the two outlet tubes 26 shown in Fig. 3, showing that the outlets ofthe several tube units may (just as well as the inlets) be connected to one common main tube. f

The walls of the main body 5 of the` device are provided with a number ofcoo-ling chambers 6. These chambers are provided with communicating conduits or -openings 7,

8, 9, 10, 11 and 12. An inlet tube 13 com municates with the upper chamber. An outlet tube 14 communicates with the lowermost chamber. By this arrangement, a

cooling vmedium can be directed through the 12, such medium'can'be caused to circulatek through the several chambers downward to ass out throughthe outlet tube wil easily be understood. In the drawing, two series or sets of chambers 6. and com- 'ied to be controlled by more or eventually less inlet and outlet, tubes, without materially departing from the principle of this invention.

The front and rear sides of this main body Y are open. These sides are normally covered by the tube plates 15. The several cooling tubes 16 are individually expanded and eventuallyibeaded so as to firmly engage with the tube plates 15 at the rear and front sides of the device as illustrated in detail in Fig. 4 at 17. lVhen so firmly engaged with the tube plates 15, the tubes naturally are disposed within the body arranged in the desired' manner.

End or 'cover plates 18 are provided to close or suitably cover the open ends of the tubes. Such plates 18 are provided with return pockets 19, arranged in such a manner in the closing surface of` the plates that a suitable number of tubes can communicate l in a consecutive manner so as to make such number' of tubes an independent unit. The sectional illustration of Fig. 3 is so arranged, according to the section lline 3 3 in Fig. 1, as' to bring out that the two units have each a separate inlet and outlet; in Fig. 1, the units beingV illustrated as having and occupying three rows of pipes, one row of pipes above another row of pipes, four pipes in a rowI in a unit; but it will easily be understood that the'number of pipes illustrated in the drawing have only been chosen to make the 'device appear clearly in the drawing, that, however, more pipes can be in a row, and more rows vcan be in a unit. The cooling medium is in this manner directed and passed into one pipein one row to pass in a consecutive manner through the several pipes in that row and the following rows of that unit to finally' pass out of another pipe in the last row in that unit, as

will more clearly be described later on. Connecting ends 20 are rovided on one cover plate to form the in neetion with Fig. '24. Connecting ends 21 are provided in the saine cover plate to form.

Such inlets and outlets are arthe outlet. ranged so as to come into alignment with oneof the tubes ever so. often as can clearly be seen in Figsnl, 2 and 3.' In Fig. 1, the

ytube indicated at 22 is in alignment with one of suchinlets in the cover plate, and the tube 23 is in alignment with one ofthe outlets,.so that all the tubes between the points 22 and 23, designated by the numeral 24, form one independent unit, the several tubes 16 in this unit 24 communicating through the return pockets 19 in the 'cover plates 18.

et, see Fig. 3 in conof this unit towards the rear through the return pocket 19 in the rear cover plate 18 over to thel third tube in the lower row of that unit; through the third tube in the lower row towards the front; through the return pocket 19 in the front cover plate-18 over to the fourth tube of the lower row; through the fourth tube towards the rear; through the return pocket in the rear cover plate over to the .fourth tube in the row above the row of tubes just referred to;

through the four tubes in this second row, l

and through the return pockets in the front and rear cover plates in a similar manner as described'with reference to the first row; through the return pocket in the rear cover plate over to the first tube in the row above the row of tubes just referred'to; through the four tubes in this third row of tubes, and through the return pockets in the front 'and rear cover plates in a similarmanner as described with-reference to the first row of tubes; and from the fourth tube in this third row of tubes out through the outlet 21, see Fig. 3; the tube indicated a-t 22 in Fig. 1 communicating with the inlet 20, indicated in Fig. 3, and the tube indicated at 23 in Fig. 1 communicating with the outlet 21,'indicated in Fig. 3. v

All the inlets are preferably connected to a common inlet tube 25, and all the out-lets are preferably connected to a common outlet tube 26. .In the drawing there beingshown two such outlet tubes 26, sincethe outlets are illustrated further apart, but, of course, the outlets'too may and can be arranged with similar bends as illustrated'on the inlets so that onev common outlet tube can befused to receive' connections from all outlets, as will easily be understood from the fragmentary' illustration in'Fig. `7 without further illustration and explanation.

Each outlet and inlet connection is preferably provided with an individual valve 27 so that each such connection can be shut off from the common inlet and outlet tubes. Between the valvesion the one side and the inlets and the outlets on the other side, proper union connections must, of course,

be provided so that the cover plates can be' up ,the passing substances, as vapors and other substances passed through the device for cooling and condensing purposes, and to further facilitate ,the operation of the de vice. Such plates Q8 are normally of plainl sheet metal and are perforated to allow the passing of such substances through the de- VlCe;

Any substances to be treated in the device are passed in at 29 and discharged at 30, so that such substances have to `pass through the several perforated plates 28 and around the several tubes 16 in the several units.

IVhen the deviceis being used for cooling and condensing purposes,y the matter to be cooled passing through the device from end 29 to end 30, a cooling medium must naturally be passed through the tubes 16 in the pat-h of the matter to be cooled.

It is very common that a device of this type becomes'leaky, or that one or another of the tubes becomes defective or clogged up.

To oversome such defects in devices of this type, and to avoid a putting out of commission of the whole device, the cooling tubes are arranged in units, and the units are arranged so that any of the units may be inspected without` influencing lthe other units during the operation of-the device, as described above.

The bolts 31l are provided to hold the whole device together, that is to secure theV the tube sheets 15 and the cover plates 18 to the side Walls.` For properly sealing up the device, and, since the individual cover plates 18 are to be removed one independently of the other, to make a good water and vaportight device even during the time when one,A or the other of the cover. plates is removed,

it is naturally necessary that some of the bolts 31 be used for sealing and securing the tube sheets to the body, as indicated at 35 in Fig. Q, while other 4bolts are provided for the holding of the cover plates alone, as

indicatedat 36. Such bolts can, however, be`

modified in quite anumber of slightly different forms. One form is illustrated in Iiig. 5, the bolt -37' being provided with shouldermembers 38 for separately securing the tube sheets tothe body and receiving the cover vplates outside of the shoulderl member to be held by eXtra nuts 39. Such slight di'erences in the arrangements are of coure immaterial and only a matter of cony venience 1n assembling ,the device, and, since kj that kind of stud-bolts are known 1n` so many different shapes and designs' to any mechanic, such fastening, securing and assembling as well as taking apart will be understood without further detail illustration and explanation of specific forms of bolts. The bolts 32 are illustrated in Fig. 3 as passing' through the whole device for holding the outside cover plates. This also will he. understood not to be necessary since short stud-bolts can just as well besecured within tht tube sheets to allow a `securing y of the cover plates to the tube sheets by such short stud-bolts as illustrated in Fig. 6. Other minor detail parts are not illustrated since all are well known to any mechanic, and, since no detail claim of such minor connecting partsl are made, this speciiication will be sufficient to make this application un derstood to 'any one interested in devices of i this kind.

It will also easily be understood 'that slight' modifications can be arranged `without departingfrom the spirit of this inven tion and that I do not wish to limit myseli to the specific construction as illustrated in `the drawing, but only to matter as' far as may be connected in parallel to common in`r means for controlling the -iiow of cooling fluid through each unit.

2. In a device of the class described, a body having a passage therethrough and havingcooling chambers within its walls, and cooling tubes disposed crosswise through the passage in the body and having outside connectionstor independently pasing a cool-l let and outlet manifolds, and `independent ing medium through certain numbers of the tubes.

3. lIn a device of lthe class described, a body having a passage therethrough, tubes disposed crosswise through the passage in the body, cover plates having a number of return pockets to form end communications between adjacent tubes and having a number of inlets .and outlets, an inlet and an outlet embracing a number of return pockets so, as to form a tube unit between each v'said pair, each unitchaving independent outside inlet and outlet connections, an inlet manifold connected with the several inlet connections of the several units, an outlet manifold -having communication with the several out* sheets betweenthe cover plates and the body supporting the several tu e ends.

4. In a device of the class described, a

vbodyhaving a passage therethrough, tubes disposed crosswise'through the passage in the body, cover plates having a number of returnpockets to form end communications between adjacent tubes and having a number *let` connections of the several units, tube f of inlets and outlets, an inletand an outlet embracing a number of return pookets so as to form aftube unit between eaeli said pair, each unit having independent inlet and outlet connections outside of the body, an inlet manifold having communication with the several inlet Connections of the several units, an outlet manifold having Communication with the several outlet connections of the several units, means for controlling the each unit, tube sheets between the cover plates and the body for supporting the several tube ends, and perforated plates disposed in the passage of the body and between the several units.

In testimony that I claim the foregoing as my invention I have signed my name in the presence of two subscribing Witnesses.
